See Japanese Utility Model Laid-Open No. 6-823). In this type of device, the air conditioner is driven to charge the interior of the vehicle in advance from the time when charging of the battery is completed. Generally, about 5 kW of electric power is required to charge a battery of an electric vehicle, and about 2 kW of maximum electric power is required to operate an air conditioner.
For this reason, about 7 kW of electric power is required if pre-air conditioning is performed while charging the battery of an electric vehicle in a general home.
At 00V, a large current of about 70A flows. for that reason,
There is a problem in that a large capacity power supply line must be provided, which increases equipment costs. Therefore, in the above device, the power supply capacity is suppressed to about 5 kW by operating the air conditioner after the battery is completely charged, and the facility cost of the power supply line and the like is suppressed.

正している。There is also known a vehicle air conditioner in which the air conditioning control characteristics are sequentially corrected according to the occupant's sense (see, for example, Japanese Patent Laid-Open No. 3-54015). In this type of device, when the occupant manually changes the air volume or the like before reaching the reference point set in the control characteristics of the automatic air conditioner, the reference point is sequentially corrected according to the degree of change.

電して空調時間が足りなくなることもある。However, in the former air conditioner for an electric vehicle described above, since the air conditioner is started after the charging of the battery is completed, sufficient air conditioning cannot be performed if the charging is prioritized. There arises a problem that a desired thermal environment cannot be created in the passenger compartment before the vehicle is used. Also, if air conditioning is prioritized, the battery charge rate will decrease,
This causes a problem that the travelable distance is reduced and the action range is reduced. Whether to prioritize charging or air conditioning depends on the user and the situation, so if you set a unique priority from the beginning, you will air-condition longer than necessary or run only a short distance. In some cases, the air conditioning time may run out by charging more than necessary.

It is conceivable to obtain control characteristics. However, there is a problem in that the characteristics of the occupant's settings cannot be accurately extracted by simply combining the former pre-conditioning and the latter conditioning control. This is because, in the latter air conditioning control, the air conditioning control characteristics for a certain thermal environment are corrected based on the operation of changing the occupant who actually senses the control output. This is because it is not possible to sense and judge the actual control output. Therefore, it is necessary to predict the control result by some method and ask the occupant to make a judgment on the result.

をすべて精度よく学習させる必要がある。Further, in the air conditioner for an electric vehicle, it is not preferred to change the setting of the occupant because securing a sufficient charge amount commensurate with the traveling distance is prioritized over the preference for the thermal environment. Often. For this reason,
It is difficult to accurately extract the passenger's preference for the thermal environment. Further, the daily mileage varies depending on the user, and the power consumption differs between the mountain road and the urban area even with the same mileage. Normally, a user who travels only a short distance and does not need a full charge sets the charging priority even though he / she can prefer the pre-conditioning, so he / she learns not to pre-condition. there is a possibility. Furthermore, climate characteristics such as whether the surroundings of the parked vehicle are hot or cold, indoors or outdoors are unknown at the time of vehicle development, and the choice of air conditioning during charging is left to the user. It will be. However, if the user has no knowledge of the most energy-efficient air conditioning method, insufficient charging may occur.
That is, it is necessary to accurately learn all of the thermal environment characteristics of the surroundings during parking, the usage characteristics of the charging device based on the traveling pattern, and the pre-air conditioning setting characteristics.

If the pre-air conditioning is impossible, the process proceeds to step 812, and if it is possible, the process proceeds to step 813. In step 812, a display for prompting the user to change the setting is displayed. In this display, as shown in FIG. 11, the fact that pre-air conditioning is not possible is displayed on the display unit 31 as a graph in which the length is changed according to the degree of possibility of pre-air conditioning, so that the possibility for the user is increased.

くとることが可能となる。Next, the charging and pre-air conditioning execution processing will be described with reference to the flowchart of FIG. In step l301, the prior air conditioning priority calculated based on the history of the user's prior air conditioning settings stored in the storage device 17 is input. In the subsequent step l302, the planned travel distance of the previously set travel schedule, the power consumption calculated from the average power consumption per unit travel distance stored in the storage device 17, and the prior air conditioning priority calculated in step l301. Based on and, the target charging rate that should be charged at least at the start of use is calculated. That is, first, the minimum required charging rate for traveling the planned traveling distance is calculated. Next, the required charging rate is multiplied by a predetermined rate according to the prior air conditioning priority to obtain the target charging rate. In this embodiment, the multiplication factor used for the calculation is set to be smaller as the prior air conditioning priority is higher, as shown in FIG. Therefore, a user who tends to give priority to charging rather than pre-air conditioning has a larger target charging rate than a user who gives priority to pre-air conditioning, and accordingly can use a larger amount of power available for traveling. .

If it exceeds, the process proceeds to step l304 to display the end of charging. In step l305, it is determined whether or not the pre-air conditioning is selected. If it is selected, the process proceeds to step l307, and if it is not selected, the process proceeds to step l306. In step l306, it is determined whether or not the charging is over the target charging rate, and if it is over, the process proceeds to step l307. In this case, even if the charging is already completed and the pre-air conditioning is not selected, the pre-air conditioning is performed to improve the comfort when riding. In step l307, the vehicle compartment temperature is input from the room temperature sensor 4. When a measuring device such as an outside air temperature sensor or a solar radiation sensor is also used as the thermal environment measuring means, thermal environment information such as the outside air temperature and the amount of solar radiation is input from these measuring devices. In the subsequent step l308, the input thermal environment information is stored in the storage device 17. In step 1309, the room temperature at the scheduled boarding time is predicted from the input thermal environment information, the past thermal environment history, and the current air conditioning schedule.
In step 1310, the difference between the predicted room temperature and the set room temperature is calculated. If the difference is large, it is determined that the current air conditioning schedule needs to be changed, and in step 1311, the optimum air conditioning schedule is set. However, when the pre-air conditioning is not selected and the set room temperature is not input, the average value of the set room temperatures at the same time in the past stored in the storage device 17 is used as the present set temperature. In step l312, the setting of the current time of the air conditioning schedule is output to the air conditioning control amplifier 7.

At 508, the history stored in the occupant setting history area of the storage device 17 is averaged for each thermal environment to create an air conditioning setting map for each thermal environment condition. The air conditioning setting map is shown in Fig. 18.
As shown in, the set average value of the set room temperature is stored for each of the outside temperature and the amount of solar radiation. However, in a region of thermal environment conditions that has not been experienced, the initial value is a predetermined value such as 25 ° C.

可能となる。Next, each processing and effect described above will be described along with the operation procedure of the user. (1) First, when the user connects the charging power supply connector 14 to the household power supply from the vehicle, sets the charging / setting changeover switch 33 of the pre-occupant setting device 15 to the setting mode, and inputs the travel schedule and pre-air conditioning settings. The pre-air conditioning setting support device 16 displays the degree of necessity of pre-air conditioning based on the history of the thermal environment in which the vehicle is parked. (2) When the pre-air conditioning is selected, the required traveling power obtained from the predicted value of the power consumption based on the past traveling information and the current charging rate, and the air conditioning power required to reach the set room temperature The total required power is calculated, and it is determined whether this required power can be supplied from the household power supply by the scheduled boarding time, and the result is displayed. At this time, since the learned value of the power consumption calculated from the history of the past driving information is used, it changes individually due to changes in vehicle characteristics over time, driving environment, driving characteristics of the user, etc. Appropriate information that takes into account generations is provided. (3) Next, the user sees the possibility of the pre-air conditioning displayed, and if the possibility is low, the user selects an appropriate item from the candidates of the selection item displayed next and changes the setting. . Here, the display screen displays how much each selection item should be changed in order to enable pre-conditioning, so that the user can easily determine the amount of change by referring to the information. . (4) When the setting during charging is completed by the above setting mode and the operation mode is switched to the execution mode, the operation schedule of charging and the air conditioning control device up to the scheduled boarding time is created, and the control amount according to each time is created. Is output. However, even during the execution mode period, the schedule is sequentially reviewed according to changes in the charging state and the thermal environment at each time point, and the optimum control amount is calculated. In addition, charging ends when the target charging rate calculated from the past travel information history and the prior air conditioning priority is reached, and power is supplied for the prior air conditioning until the start of traveling.
This target charging rate has a large average power consumption of driving information,
The lower the priority of pre-air conditioning, the higher the setting. Therefore, in the case of a vehicle that normally consumes a large amount of electric power for traveling, charging becomes important, and the charging rate at the start of traveling is set high. Further, even in the case of a user who has a large deviation between the planned traveling distance and the actual traveling distance stored in the past traveling information history, the target charging rate is set high according to the deviation. As a result, it is possible to cope with individual differences in the difference between the preset amount and the usage amount, and for users who tend to set more than necessary, lower the target charging rate and often run longer than the planned distance. In the case of a person, increase the target charging rate. After starting traveling, the storage device 17 stores the settings at each time.
Sequentially stores in the setting storage history area of, and performs averaging processing after use is finished, and is used when performing pre-air conditioning setting support, charging, and pre-air conditioning. As a result, it becomes possible to perform optimal pre-air conditioning according to the past air conditioning settings of the occupant.

テゴリウェイトａi(i=1,…，K)を用いた線形式-Second Embodiment- In this second embodiment, fuzzy inference is used to calculate the discriminant function used as knowledge when calculating the prior air conditioning priority. That is, as shown in FIG. 19, the data stored in the pre-air-conditioning setting history area of the storage device 17 is stored in FIG.
Fuzzy average as a category for each item. The meaning of the numerical values in FIG. 19 is the power consumption conversion ratio of each setting item change in the changed total power. Xik in Figure 20
(I = 1, 2, 3, k = 1, 2, 3) is the storage device 17
The numerical value of each setting item in the pre-air conditioning setting history area is the frequency included in the numerical range of each category. Then, a predetermined weight is applied to each category to calculate the sum of the determination scores, and the preliminary air conditioning priority is calculated using the relationship between the determination score and the preliminary air conditioning priority shown in FIG. The relationship between the weight of each category in FIG. 20 and FIG. 21 is determined at the time of development. That is, the prior air-conditioning priority is given a priori for several standard change patterns, and the generally known fuzzy quantification type 2 theory (exhibited by Watada et al., Behavior Metrics vol.9, No.
2, (1982), pp. 24-32, etc.) is used to calculate the discriminant function for calculating the category weight and the prior air conditioning priority. It is assumed that there is data having the structure shown in the table of FIG. B r (r = 1,
, M) is called a fuzzy external reference, and is a set of elements to be separated by a discriminant to be finally obtained, and corresponds to the prior air conditioning priority of the present embodiment. These are [0,
In the present embodiment, there are two fuzzy groups of the air conditioning priority type and the charging priority type. A i (i = 1, ..., K) is a plurality of categories of several items arranged in order, and corresponds to the category shown in FIG. 19 in the present embodiment. The purpose of the fuzzy quantification type 2 theory is to use a line form using category weights a i (i = 1, ..., K) for each category A i.

盛り込むことも可能である。Η 2 = B / T where B is the fuzzy variance ratio between groups and T is the total fuzzy variance ratio. The calculation of a i is performed by transforming the relational expression in which the value of FIG. 21 is substituted into the mathematical expression 2 and reducing it to the eigenvalue problem of the matrix, as shown in the literature of the previous exhibition. When a i is obtained, the discriminant score y (ω) in the linear form (Equation 1) of each sample can be calculated, and the correlation formula for calculating each external reference value according to the discriminant score is as shown in FIG. It can be obtained in various forms. In this embodiment,
The knowledge of FIG. 19 obtained about the prior air conditioning priority is used for actual control. By using the method of this embodiment,
As compared with the method of directly calculating the prior air conditioning priority by a simple linear sum of the weights for each factor, it is possible to perform the calculation in accordance with the human sense, and it is possible to accurately predict the prior air conditioning priority of the user. Further, in the present embodiment, only the actual operation of the user is used as a factor for calculating the prior air conditioning priority, but it is also possible to include, for example, a questionnaire result regarding the prior air conditioning of the user.

Correct the temperature. That is, at the time of creating the air conditioning schedule in step 1309 shown in FIG. 13 of the first embodiment, as shown in FIG. 24, the occupant setting room temperature average value during traveling, which is stored in the occupant setting history area of the storage device 17, and the default value are set. The larger the difference from the value and the larger the predicted running power consumption value, the larger the set room temperature correction amount for pre-air conditioning. As a result, the room temperature at the start of traveling can be made lower during cooling and higher during heating, and the power consumed for air conditioning during subsequent traveling can be reduced.

Thermal environment predicted value in the vehicle interior at the travel start time, battery charge state, travel start time and target vehicle interior thermal environment,
Display the support information for the passenger to set the pre-air conditioning based on the current time and the thermal environment, determine the pre-air conditioning priority based on the history of the pre-air conditioning setting information history for the support information, and set the pre-air conditioning priority. Based on this, the support information is changed and the operation of the air conditioner is corrected, so that the vehicle interior at the start of use according to the air conditioning settings preferred by the occupant while ensuring the charging rate that matches the usage characteristics of the vehicle. The environment can be achieved. Further, when storing the air conditioning setting history, the necessity of pre-air conditioning is displayed based on the difference between the thermal environment predicted value and the target vehicle interior thermal environment, and the charging rate predicted value at the travel start time, the travel information history and the air conditioning The possibility of pre-air conditioning is displayed based on the set thermal environment and the history of change items and amount of change in the air conditioning settings of the occupant after the display is stored together with the necessity and possibility of pre-air conditioning. , It is possible to accurately grasp the tendency of air conditioning changes to the necessity and possibility of advance information of the occupant, and by using these setting history for the next pre-air conditioning control, the occupant of the occupant can be secured while securing the necessary charge amount. The desired pre-air conditioning can be achieved. If the prior air conditioning priority is calculated by a linear sum obtained by weighting the average of the air conditioning setting history records, a more accurate prior air conditioning priority can be calculated. Also, from the air conditioning setting change history, each setting change is divided into a plurality of setting change ranges, the frequencies corresponding to the respective ranges are calculated, and a linear sum is calculated by multiplying each frequency by a precalculated weight. , If the pre-air conditioning priority is calculated by the correlation function of the pre-calculated linear sum and the pre-air conditioning priority,
It is possible to calculate the prior air-conditioning priority that better suits the human sense.
In addition, the target set room temperature for pre-air conditioning is corrected based on the average set room temperature during running and the average running power consumption, so the room temperature at the start of running can be set low during cooling and high during heating. Therefore, it is possible to reduce the power consumption for air conditioning during the subsequent traveling.
